Wifi Setup


Recommended Posts

Hello and sorry if I posted on the wrong dubforum but I need some advice in setting up my Wifi connection.The brand and model of my Modem is Skyworth CM5100. The set up is as follows: ISP > Wireless Modem > End Devices. I have my Window's firewall enabled, but I didn't know that Modem and Routers have Firewalls too. When I snooped around, I saw that the firewall is in the low settings. I wanna ask what changes do I need to do? I have some of the options here and want to ask what should I enable or set them.
IPv4 Firewall Protection: Off/Low/Med/High

IPv6 Firewall Protection: On/Off

Filter Proxy: Enable/Disable

Filter Cookies: Enable/Disable

Block Fragmented IP Packets: Enable/Disable

Port Scan Detection: Enable/Disable

IP Flood Detection: Enable/Disable

I'm not sure if these settings will affect some of functions of my Wifi, but I play online games such as Valorant, League of Legends in garena, Teamfortress 2 and other Steam games, as well as watch streams on Netflix, Youtube and Cmovies.

Any advice is welcomed. Thank you!

In my Wifi's Low Firewall Setting, it said that No Ports are Restricted

Firewall Protection defaults to the most common TCP/UDP ports being allowed through.

There are legitimate functions and games that may use un-common TCP/UDP ports and would require a "Firewall Rule" to allow it or them through.

You can stay at Low.   Or... you'll have to create Rules in Medium mode that would allow a specific TCP/UDP port allowance or a range of ports to be allowed through.

Thank you for the help, you have mentioned to me that I should block some Ports and blocked them with the Port Filtering in our router, I have a question, it is said that with my Firewall being enabled be it low or medium, it protects me from Denial of Service Attacks. Am I safe even if it's in the low setting?

Individuals are rarely the target of a DoS attack unless you are a High Value Target. 

You'd have to read the Router's manual.  I could not easily find it.

Owning and managing one's own Modem+Router puts the security in one's own hands and, depending upon the ISP, may save a monthly Rental charge.

You'd have to check with your ISP.  Some have an authorized list of appliances and may require providing the appliance MAC address to the ISP to get access into their network (aka; MAC Authentication).

Yes, 100% true. You need to make certain that your ISP will allow you to have and use your own router before you even consider buying one.

Cheers and good luck
